As a behavioral economist, I study how people make decisions and how they can be motivated or nudged to "do the right thing." I aspire to increase the welfare of individuals and society through behavioral insights and evidence-based decision making. I mostly work on the topics of environmental sustainability, health and charitable giving. 


I am currently an Assistant Professor at the Department of Economics at the University of Copenhagen. I am affiliated with the Center for Economic Behavior and Inequality (CEBI) and I am one of the directors of the Copenhagen Experimental Laboratory. I am a CESifo Research Network Affiliate and advisory board member of the Society for the Advancement of Behavioral Economics


Most of my time is spent doing research on the feasibility of behavioral interventions and on understanding how our beliefs about ourselves, as well as our decision environment, affect our behavior. I work both in the field, in collaboration with organizations, and with students in the laboratory. When I am not doing research I am teaching Game Theory, an elective on Science of Behavior Change, a Master's course on Field Experiments, a seminar course on Behavioral Economics in Action, and supervising students on the Bachelor's, Master's, and Ph.D. level. 


You can find more information about my publications, my work in progress, and where we might have met on the next pages or you can download my Academic CV.


I am the Co-Founder of Impactually, a behavioral science management consultancy. I have trained hundreds of executives in behavioral science methods, given keynote lectures on behavioral economics in practice, and consulted the private, public, and non-profit sectors on how to integrate behavioral science in their work. I was selected as one of Berlingske's Talent 100 2019
